Interpretation of inflammatory markers in lung cyst hydatid disease.

Studies on alterations in inflammatory markers and risk factors for perforation in hydatid cysts of the lung are rare. In our study, we planned to investigate the effect of inflammatory markers on prognosis of hydatid cyst disease. 37 patients underwent surgery for pulmonary hydatid cyst between February 2022 and October 2023 and analyzed retrospectively. Inflammatory markers were calculated from preoperative and postoperative 3rd-month peripheral blood results. Cyst size was 58.5 ± 28.0mm, 5 patients had bilateral cysts and 11 patients had multifocal cysts. Preoperative white blood cell, white blood cell difference, preoperative and postoperative eosinophils, preoperative neutrophils, neutrophils difference, preoperative systemic immune inflammatory index, systemic immune inflammatory index difference and preoperative eosinophil lymphocyte ratio were higher in patients with perforated cysts, the cut-off value for preoperative white blood cell for perforation was 10,535, preoperative cut-off value for eosinophils was 230, preoperative cut-off value for neutrophils was 8815, the cut-off value for preoperative systemic immune inflammatory index was 1129.83 and the cut-off value for preoperative eosinophil-lymphocyte ratio was 0.09. In patients with preoperative eosinophil, neutrophil, white blood cell, eosinophil-lymphocyte ratio and systemic immune inflammatory index values above the cut-off value, the probability of perforation increased 7.5, 13.6, 6.3, 9.6, and 9.3 times, respectively.

Recovery of muscular tissue and functional results of patients treated with a gluteus maximus flap transfer due to chronic abductor deficiency after total hip arthroplasty.

To evaluate the function of the abductor mechanism after a gluteus maximus flap transfer due to a degeneration of the muscles after hip arthroplasty, we analyzed the post-operative functional outcome as well as radiographic effects in muscle tissue. This present study included six consecutive patients operatively treated with a gluteus maximus flap due to chronic gluteal deficiency after total hip arthroplasty. All patients presented a preoperative severe limp, hip abductor deficiency and a history of conservative treatment without the relief of symptoms. MRI scans were performed pre- and postoperatively to evaluate the muscle volume and grade of degeneration of the abductor mechanism. For clinical evaluation, the Harris hip score (HHS) was applied pre- and postoperatively. Moreover, the intensity of pain, the Trendelenburg sign, the internal rotation lag sign and the abductor muscle force were measured before and after surgery. Overall, the evaluation of the Magnetic Resonance Imaging (MRI) showed no significant changes in total muscle volume during the follow-up period. Separate measurements presented a significant growth of muscle volume for the gluteus minimus and tensor fascia lata compared to preoperative imaging during the follow-up period. The amount of fat volume decreased for all the measured muscles with statistical significance for the gluteus minimus, the gluteus medius and the tensor fascia lata. No further muscle degeneration and no flap necrosis were measured. The postoperative HHS results were not statistically significant compared to the preoperative results. Besides fair clinical results, the radiological measurements indicate that the flap transfer enables functional muscular tissue recovery and prevents further degeneration. Given these conditions, the gluteus maximus muscle flap transfer represents a viable treatment option for patients with chronic gluteal deficiency in selected patients.

Learning curves for high tibial osteotomy using patient-specific instrumentation: a case control study.

Three-dimensional (3D) planning and Patient Specific Instrumentation (PSI) can help the surgeon to obtain more predictable results in Medial Opening Wedge High Tibial Osteotomy (mOW-HTO) than the conventional techniques. We compared the accuracy of the PSI and standard techniques and measured the learning curve for surgery time and number of fluoroscopic shots. We included the first 12 consecutive cases of mOW-HTO performed with 3D planning and PSI cutting guides and the first 12 non-supervised mOW-HTO performed with the standard technique. We recorded surgery time and fluoroscopic time. We calculated the variation (Δ delta) between the planned target and the postoperative result for Hip Knee Ankle Angle (HKA), mechanical medial Proximal Tibia Angle (MPTA), Joint Line Convergence Angle (JLCA) and tibial slope (TS) and compared it both groups. We also recorded the complication rate. We then calculated the learning curves for surgery time, number of fluoroscopic shots, Δ from target in both groups. CUSUM analysis charts for learning curves were applied between the two groups. Mean surgical time and mean number of fluoroscopic shots were lower in PSI group (48.58±7.87 vs. 58.75±6.86 min; p=0.034 and 10.75±3.93 vs. 18.16±4.93 shots; p<0.001). The postoperative ΔHKA was 0.42±0.51° in PSI vs. 1.25±0.87° in conventional, p=0.005. ΔMPTA was 0.50±0.67° in PSI vs. 3.75±1.48° in conventional, p<0.001; ΔTS was 1.00±0.82° in PSI vs. 3.50±1.57° in conventional, p<0.001. ΔJLCA was 1.83±1.11° in PSI vs. 4±1.41° in conventional, p<0.001. The CUSUM analysis favoured PSI group regarding surgery time (p=0.034) and number of shots (p<0.001) with no learning curve effect for ΔHKA, ΔMPTA, ΔJLCA and ΔTS. PSI cutting guides and 3D planning for HTO are effective in reducing the learning curves for operation time and number of fluoroscopic shots. Accuracy of the procedure has been elevated since the first cases.

Comprehensive Classification of the Capitellar Injury Concurrent with Radial Head Fracture.

Capitellar injury (CI) includes capitellar cartilage injury (CCI) and capitellar fracture (CF). A comprehensive classification of CI concurrent with radial head fracture (RHF) that can guide surgical strategy is lacking in the literature. Therefore, this study aimed to introduce a comprehensive classification of CI concurrent with RHF and investigate its value. A total of 35 patients with CI concurrent with RHF confirmed by surgical exploration were retrospectively analyzed, includingmales in 19 cases and females in 16 cases. RHF was classified according to the Mason classification, and CI was classified into six types, including 3 types of CCI and CF, each based on the site and degrees of injuries (comprehensive classification method proposed in this study). The classification results were analyzed. Two radiologists were selected to independently classify the CI, and the inter- and intra-observer agreements were analyzed with kappa statistics. Mason Type I, II, III, and IV RHF accounted for 14.3%, 48.6%, 37.1%, and 0% of cases, respectively. Type I, II, III, IV, V, and VI CIs accounted for 22.9%, 34.3%, 25.7%, 11.4%, 2.9%, and 2.9% of cases, respectively. Therewas no obvious relationship between the CI and RHF types (p > 0.05). All Type I CIs underwent removal, 9 Type II CIs underwent microfracture repair, and 3 Type II CIs underwent removal. All Type III CIs underwent fixation, one Type IV CI underwent removal, and 3 Type IV CIs underwent fixation, one Type V CI underwent fixation, and one Type VI CI underwent arthroplasty. The inter- and intra-observer kappa coefficients were 0.830 ~ 0.905 and 0.805 ~ 0.892, respectively. At 12 months postoperatively, the elbow function evaluated by MEPS was 91, with an excellent and good rate of 97%. Different types of CI differ not only in pathology but also in treatment methods. The CI comprehensive classification put forth in this paper for the first time reflects different types of pathology well, with high consistency and repeatability, and can guide the selection of surgical methods, leading to satisfactory postoperative results.

Foramen Magnum: Morphometric Analysis in Dry Adult Human Skulls

Abstract Background: Foramen magnum (FM) is a crucial aperture situated in the occipital bone and connects the brain to the spinal cord. Its size and dimensions are crucial in understanding a range of disorders, with implications for clinical, surgical, radiological, and forensic fields. We undertook the present study to analyze the morphometry of FM in detail and to compare this data with other similar studies. Methodology: This study analyzed 51 dry human skulls from Northern India of unspecified gender. Morphometric assessments of the FM were conducted, encompassing measurements of its shape, anteroposterior diameter (APD), transverse diameter (TD), FM index (FMI), size, and surface area using digital Vernier calipers. Minimum, maximum, and mean values and standard deviations (SDs) were calculated for each parameter. A comparison with previous studies was conducted. Results: The study established that the most common shape of FM as calculated by the ratio of AP diameter to TD was round (58.8% of specimens) and the majority of FM (41.1%) were narrow according to Martin and Saller classification. Mean APD was 33.71 ± 2.53, and TD was 27.88 ± 1.92; AP diameter was significantly greater than TD (P &lt; 0.05). FMI ranged from 70.54 to 93.55 (mean: 82.92 and SD: 5.63). The mean surface area as calculated by Teixeira’s method was higher compared to Radinsky’s formula; 747.51 ± 96.25 mm2 and 739.93 ± 94.85 mm2, respectively. This difference was not statistically significant (P = 0.68). Conclusion: This study furnishes data on detailed morphometry of FM, a complete knowledge of which is essential for planning surgical procedures for optimal preoperative and postoperative results. It provides an objective definition of the FM’s morphology and highlights the ambiguous role of visual assessment which needs to be reconsidered. The comparison of present morphometric data with other national and international studies further highlights the ethnic and genetic variation of FM.

Comparative study of the early functional outcome of anatomic reconstruction of chronic lateral ankle instability with polyester tape reinforcement versus anchor repair

Purpose This study aims to compare the early functional outcome of anatomic reconstruction of chronic lateral ankle instability with polyester tape reinforcement versus suture anchor repair. Patients and Methods Sixty patients suffering from chronic lateral ankle instability were included. Thirty patients were treated by anatomic reconstruction of the injured ligaments and reinforcement with polyester tape and the other half was treated by suture anchors in our institution with a minimum period of 6 months follow-up. The postoperative results were assessed according to the American Orthopedic Foot and Ankle Surgery (AOFAS) scoring system for hind-foot. Results AOFAS score is improved postoperatively in both techniques without statistically significant difference (P=0.084). The results of the two techniques were comparable without statistically significant difference regarding pain, walking distance, hindfoot motion, foot alignment, activity limitation and support requirement (P=0.602, 0.067, 0.582, 0.448, 0.606, respectively). All the studied cases returned to their original activity level.

Applications and accuracy of 3D-printed surgical guides in traumatology and orthopaedic surgery: A systematic review and meta-analysis.

Patient-Specific Surgical Guides (PSSGs) are advocated for reducing radiation exposure, operation timeand enhancing precision in surgery. However, existing accuracy assessments are limited to specific surgeries, leaving uncertainties about variations in accuracy across different anatomical sites, three-dimensional (3D) printing technologiesand manufacturers (traditional vs. printed at the point of care). This study aimed to evaluate PSSGs accuracy in traumatology and orthopaedic surgery, considering anatomical regions, printing methodsand manufacturers. A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Studies were eligible if they (1) assessed the accuracy of PSSGs by comparing preoperative planning and postoperative results in at least two different planes (2) used either computer tomography or magnetic resonance imaging (3) covered the field of orthopaedic surgery or traumatologyand (4) were available in English or German language. The 'Quality Assessment Tool for Quantitative Studies' was used for methodological quality assessment. Descriptive statistics, including mean, standard deviation, and ranges, are presented. A random effectsmeta-analysis was performed to determine the pooled mean absolute deviation between preoperative plan and postoperative result for each anatomic region (shoulder, hip, spine, and knee). Of 4212 initially eligible studies, 33 were included in the final analysis (8 for shoulder, 5 for hip, 5 for spine, 14 for knee and 1 for trauma). Pooled mean deviation (95% confidence interval) for total knee arthroplasty (TKA), total shoulder arthroplasty (TSA), total hip arthroplasty (THA)and spine surgery (pedicle screw placement during spondylodesis) were 1.82° (1.48, 2.15), 2.52° (1.9, 3.13), 3.49° (3.04, 3.93)and 2.67° (1.64, 3.69), respectively. Accuracy varied between TKA and THA and between TKA and TSA. Accuracy of PSSGs depends on the type of surgery but averages around 2-3° deviation from the plan. The use of PSSGs might be considered for selected complex cases. Level 3 (meta-analysis including Level 3 studies).

Mesh-like External Suture Splint: A Way to Improve Results and Reduce Postoperative Complications after High-definition Liposculpture.

High-definition liposculpture with variable degrees of muscular definition allows both patients and surgeons to broaden the procedure to fit almost any individual preferences; however, skin laxity and those secondary cases still represent a big challenge for the surgeon to achieve optimal outcomes. We are reporting our experience with a new suture-splint procedure to reduce edema, avoid skin laxity, and increase muscular definition after liposculpture. We enrolled patients undergoing HDL with any risk factor that could compromise aesthetic outcomes. Tumescent technique with VASER fat emulsification and power-assisted liposuction were used to complete HDL. We performed a continuous suture over the midline and other areas of muscular definition right before patients awakened from anesthesia. Real-time ultrasound imaging was performed to ensure the safety of the procedure. A total of 52 consecutive patients were treated with MesHD in our study. Only two patients voluntarily dropped off from postoperative analysis due to geographical limitations. Postoperative edema was referred by only one patient after surgery. No major complications were reported. Three patients complained of stabbing pain over one of the stitches, which resolved completely after suture removal. All patients were satisfied with postoperative results. Mesh suture-splint at body areas with high risk of adverse effects after body contouring surgery may be an effective procedure to improve recovery by decreasing edema formation, enhancingmuscular definition, decreasing risk of fibrosis, and avoiding skin laxity postoperative appearance.

Double-level osteotomy for varus knees using patient-specific cutting guides allow more accurate correction but similar clinical outcomes as compared to conventional techniques

PurposePatient-specific cutting guides are increasingly used in the field of osteotomies around the knee and can improve the accuracy of planned correction and more specifically in the case of double-level osteotomy (DLO). The purpose of this study was to analyse the accuracy of postoperative coronal alignment after DLO using patient-specific cutting guides techniques (PSI) compared to conventional techniques.The secondary objective was to compare the functional results between the two groups at short-term follow-up. HypothesisThe accuracy of global correction (HKA angle) is better with patient-specific cutting guides compared to conventional techniques for double-level osteotomy MethodsThis multicentric comparative retrospective study included 53 patients (mean age: 53.8 ± 5.2 years, male/female: 44/9) who underwent a DLO for knee varus malalignment. The coronal correction accuracy (as expressed by the difference between postoperative angular values and preoperative targeted correction) was compared between techniques using patient-specific cutting guides (PSI group, n = 27) or conventional techniques (n = 26) for the medial proximal tibial angle (MPTA) and the lateral distal femoral angle (LDFA). Postoperatively, the global alignment expressed by the hip-knee-ankle angle and the joint line obliquity were compared between groups. The postoperative functional results for KOOS and UCLA activity scale score were also compared at a mean follow-up of 1.7 years (1.0–3.1 years). ResultsNo difference was observed for the postoperative global alignment between the PSI and the conventional groups (Δ = 0.6 °, p = 0.11) neither for the postoperative posterior proximal tibial angle (Δ = 1.6°, p = 0,99) or the joint line obliquity (Δ = 0.3°, p = 0,17). In the coronal plane, the postoperative MPTA was lower in the PSI group (Δ = 2.3°, p < 0.001) as well as the postoperative LDFA (Δ = 0.9°, p = 0.01).Concerning correction accuracy in the coronal plane, the results showed a significant higher accuracy of the planned correction in the PSI group compared to the conventional group for MPTA (2.2 ± 0.2 versus 0.8 ± 0.7, Δ = 1.5 °, p < 0.001) and LDFA (1.3 ± 1.0 versus 0.6 ± 0.9, Δ = 0.7°, p < 0.001).No improvement difference was observed between the conventional group and the PSI group respectively for the KOOS symptoms (p = 0.12), the KOOS Pain (p = 0,57), the KOOS activities of daily living (p = 0.61), the KOOS sport/rec (p = 0.65), or for the KOOS Quality of Life (p = 0.99) neither for the UCLA (p = 0.97). ConclusionsThis study suggests that the use of custom-made cutting guides improves the accuracy of planned correction in double-level osteotomy compared with conventional techniques, which may have implications particularly in centers not performing a large volume of osteotomies.This improved accuracy is not associated with any difference in joint line obliquity or functional results but these results need to be confirmed by a randomized prospective study.

It is not the best option to perform transurethral enucleation of the prostate immediately after biopsy in patients with histological inflammation.

This study seeks to investigate the impact of histopathological evidence of histological prostatic inflammation (PI) on the surgical outcomes of patients with benign prostatic hyperplasia (BPH) undergoing transurethral bipolar enucleation of the prostate (BiLEP) after biopsy. We conducted a prospective study in which data were collected from 112 patients with BPH who underwent BiLEP immediately after prostate biopsy at the Department of Urology in our hospital between October 2020 and October 2023. This cohort included 52 patients with histopathological prostatic inflammation (BPH + PI group) and 60 patients with simple BPH (BPH group). Baseline characteristics, surgical details, International Prostate Symptom Score (IPSS), quality of life (QoL), post-void residual volume (PVR), maximum flow rate (Qmax), International Index of Erectile Function-5 (IIEF-5), postoperative pathology results, and surgical complications were compared between the two groups. The study findings indicate that in patients with BPH who underwent BiLEP, various parameters in the BPH + PI group including operation time, intraoperative flushing volume, hemoglobin drop value, postoperative white blood cells, postoperative C-reactive protein, and average pain score at 3 days postoperatively were significantly higher compared to those in the BPH group (p < 0.01). In addition, the IPSS and IIEF-5 scores of the BPH + PI group were significantly worse before surgery and at 2 weeks postoperatively compared to the BPH group (p < 0.01); however, no significant differences were observed between the two groups at 1 and 3 months postoperatively (p > 0.05). At 2 weeks postoperatively, the BPH + PI group exhibited significantly worse outcomes in terms of QoL, PVR, and Qmax compared to the BPH group (p < 0.01). However, there were no statistically significant differences between the two groups at 1 and 3 months postoperatively (p > 0.05). The incidence rates of postoperative complications, such as fever, prostatic capsule perforation, urinary tract irritation, bladder spasm, acute epididymitis, urinary tract infection, and urethral stricture, were higher in the BPH + PI group compared to the BPH group (p < 0.05). Nevertheless, there was no significant difference in the overall complication rates between the two groups (p > 0.05). There were no statistically significant differences observed between the two groups in postoperative irrigation volume, extubation time, hospitalization time, proportion of secondary operations, proportion of bladder injury, and proportion of urinary incontinence (p > 0.05). However, the proportion of reported prostate cancer after surgery in the BPH + PI group was significantly higher than that in the BPH group (p < 0.05). Histopathological prostatic inflammation does not have a significant impact on the long-term efficacy of BiLEP surgery immediately after biopsy. However, it does prolong surgery time, increase surgery-related complications, and influence short-term surgical outcomes and patient treatment experience. Therefore, it may be advisable to administer a course of anti-inflammatory treatment before performing BiLEP in such patients. Nevertheless, further high-quality studies are necessary to validate this approach.

Periprosthetic Transpatellar Fracture Replacement With Autogenous Iliac Graft: A Technical Note.

Periprosthetic fractures involving total knee arthroplasty (TKA) components, particularly involving the patella, can present a significant challenge regarding orthopedic surgery. This technical note outlines an approach for the reconstruction of complicated periprosthetic transpatellar fractures, with poor bone stock, utilizing autogenous iliac graft. This kind of procedure requires careful preoperative evaluation of imaging, precise intraoperative planning, and strict postoperative management to achieve adequate postoperative results. The inventive option of utilizing an autogenous iliac graft for reconstructionsuggests its potential benefits in addressing the unique biomechanical demands of patellar fractures in TKA patients with poor bone stock. Key technical aspects of this approach are highlighted and include graft harvest, graft preparation, and fixation techniques. Overall, this technique can provide a golden standard bailout for periprosthetic transpatellar fracture reconstruction and potentially offer orthopedic surgeons a comprehensive framework for addressing this challenging clinical scenario.

Use of perfusion device for free flap salvage after ischemia in swine

In free flap reconstruction, improving flap tolerance to warm ischemia (WI) is fundamental. WI is the result of a venous or arterial thrombosis, which can only be addressed through surgical revision. No additional treatments have shown superior efficacy at salvaging free flaps after or during WI. Custom perfusion machines (PM), used to reduce the intensity of lesions of the flap stored in cold ischemia, have not been evaluated for WI flap salvage. This proof-of-concept study assessed whether the Lifeport® perfusion machine could improve the salvage procedure's success rates after one hour of venous WI. Five different groups were evaluated with four porcine latissimus dorsi free flaps included in each group. Depending on the group, the flaps were subjected to one hour of WI followed by revascularization, static hypothermic submersion, or dynamic Lifeport® perfusion. Additionally, two flap perfusion liquids were evaluated: KPS-1® and IGL-1®. Biopsies were performed before in vivo warm ischemia of the flap, after in vivo warm ischemia of the flap, and after one and two hours of preservation. Interstitial edema, muscular cell size and muscular diffuse necrosis were quantified by histological assessment. Static submersion did not demonstrate any efficacy for venous flap salvage. Dynamic perfusion on Lifeport® machine showed a significant improvement in tissue parameters. Thrombi and fibrine, present during the WI period, were no longer visible inside vessels and the perfusion machine flow evacuated the inflammatory cells and their substrates from the flap. The flap weights did not increase during perfusion time, confirming the benefits of the Lifeport® perfusion machine. Evaluating Lifeport® advantages on human free flap salvage is necessary to confirm the benefits for the tissue and to increase post-operative results after congestive free flap revision surgery.

Evlaution of Different Suturing Techniques in Deep Third Molar Surgery: An Original Research

ABSTRACT Purpose: The purpose of this study was to compare the efficacy of various suturing methods used in deep third molar extraction procedures. Methods: A total of four suturing method groups—simple interrupted, horizontal mattress, vertical mattress, and figure-of-eight—were randomly allocated to 100 patients having deep third molar surgery. Assessments were conducted on wound healing, operation time, intraoperative problems, postoperative pain scores, swelling measures, and patient satisfaction questionnaires. Appropriate tests were used for statistical analysis, with P &lt; 0.05 being regarded as significant. Results: Compared to other procedures, the figure-of-eight technique showed better results in terms of postoperative pain scores, swelling measures, wound healing percentages, and patient satisfaction (P &lt; 0.05). There was no discernible difference in the operating time or intraoperative problems between the groups. Conclusion: In conclusion, there seems to be a benefit to using the figure-of-eight suturing approach for deep third molar surgery in terms of improved postoperative results and patient satisfaction. It is recommended that clinicians give this strategy some thought to improve patient care and surgical results.

Effects of Peroperative Cold Ischemia Time and Anhepatic Phase in Adult Living Donor Liver Transplant Recipients: Operation Time That is Not Affected by the Anhepatic Phase But is Prolonged by Cold Ischemia Time

ObjectiveIt was aimed to examine the overall role of cold ischemia time and anhepatic phase durations in terms of peroperative blood transfusion needs, hospital stay conditions and postoperative charges, and survival in recipients. Material and MethodsOne hundred forty-eight adult living donor liver transplant recipients (18 years and older) were included in the study. Whether the anhepatic phase and cold ischemia duration have an effect on the rates of surgery time, blood product transfusion, total hospital and intensive care unit stay, postoperative biliary complications, hepatic vein thrombosis, portal vein thrombosis, early postoperative bleeding, sepsis, and primary graft dysfunction. Was analyzed statistically. In addition, the effect of the anhepatic phase and cold ischemia time on graft survival was statistically examined by creating an average of the patient follow-up period. ResultsIt was observed that the operation time increased statistically as the cold ischemia time increased (P = .000). No statistically significant relationship was found between other findings and cold ischemia time and anhepatic phase. ConclusionProlonged surgery time due to increased cold ischemia time may be an important finding in terms of peroperative and postoperative results of the graft.

The value of arthroscopy in joint fractures of the lower limb

Introduction: Lower extremity joint fractures are common and require precise management to avoid complications. Arthroscopy offers advantages in terms of precise control, detection of associated lesions and minimally invasive surgery, thus improving post-operative outcomes. Material and methods: The retrospective study focused on 51 cases of joint fractures of the lower limb treated by arthroscopy at the Ibn Rochd University Hospital over a period of four years including : 30 ankle fractures, 20 knee fractures and a single case of hip joint fracture. The pathological study was carried out on a radiological analysis and the fractures were then classified according to the appropriate classification. Results: In the first case, a 16-year-old adolescent victim of a road accident suffered a postero-superior dislocation of the left hip, requiring emergency reduction followed by arthroscopy to remove three intra-articular foreign bodies. For the second case, knee joint fractures were observed in adults aged 20 to 55 years, mainly men, following road accidents. Surgical treatment included fracture reduction and internal fixation, with satisfactory postoperative results. Finally, in the third case, ankle joint fractures were observed in young and active adults, with a male predominance. Surgical treatment, carried out on average four days after the accident, also consisted of reduction of the fractures followed by osteosynthesis. Postoperative results were very positive, with rapid functional recovery and no complications reported. Discussion: Joint fractures of the lower limb include those of the hip, tibial plateaus and ankle. For hip fractures, more common in young adults, reduction of dislocations is crucial, often carried out under general anesthesia. Tibial plateau fractures, observed mainly in young men, require precise detection of associated lesions, which are often difficult to identify initially. As for ankle fractures, common in active adults, precise imaging, such as CT, is recommended to guide treatment, including arthroscopic screw fixation in cases of syndesmosis damage. Conclusion: Joint fractures of the lower limb are complex and require careful evaluation. Arthroscopy has revolutionized their treatment by providing precise assessment, direct reduction and treatment of associated lesions allowing rapid recovery and reduced post-operative risks compared to conventional surgery.

Predicting surgical efficacy and diagnosing histological inflammation: the clinical significance of prostate exosome proteins in benign prostatic hyperplasia.

Benign prostatic hyperplasia (BPH) is one of the most common causes of lower urinary tract symptoms (LUTS) among the aging male population. Recent studies have shown that histological inflammation (HI) plays a significant role in BPH, with prostatic exosomal protein (PSEP) identified as a potential biomarker for prostate diseases. Therefore, this study aimed to explore the effect of HI on LUTS in patients with BPH, and to further explore the clinical value of PSEP as a diagnostic biomarker of BPH complicated with HI and whether PSEP could be used as an index to predict the improvement of LUTS after operation. This study was an open-label, cohort study. The study enrolled all patients who were clinical diagnosed as BPH with LUTS and prepared to receive operation of the prostate at the Department of Urology of the Second Hospital of Hebei Medical University. International Prostate Symptom Score (IPSS) were used to evaluate the LUTS of the BPH. And the enrolled patients were divided into four groups, including none, mild HI, moderate HI, and severe HI, based on postoperative pathological results. Then the relationships between HI and IPSS, the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI), as well as PSEP were analyzed. Simple and multiple linear regression analyses were performed on the preoperative IPSS and the difference of IPSS before and after surgery was examined. SPSS software version 26 was used for statistical analysis and Prism 9.0 was used to make violin plots. A total of 69 patients were enrolled in the study. The violin plot results indicated IPSS and NIH-CPSI scores exhibited significant increases in correlation with the severity levels of HI (P<0.001; P<0.001). Among BPH patients with total prostate-specific antigen (t-PSA) levels higher than 4.0 ng/mL, a significant correlation was observed between PSEP levels and HI (P=0.04). Besides, simple and multiple linear regression analysis showed that HI (P<0.001) or PSEP (P=0.03) was significantly associated with IPSS and improvement of LUTS, assessed by postoperative and preoperative IPSS differences. The study indicated that IPSS and PSEP (when t-PSA >4 ng/mL) were correlated with the severity of HI in patients with BPH. PSEP was linearly correlated with IPSS and the degree of reduction in IPSS after surgery. Consequently, PSEP may serve as a promising predictor for assessing surgical efficacy and diagnosing the severity of HI in patients with BPH.

Comparison of Surgical Burden, Radiographic and Clinical Outcomes According to the Severity of Baseline Sagittal Imbalance in Adult Spinal Deformity Patients.

To determine the clinical impact of the baseline sagittal imbalance severity in patients with adult spinal deformity (ASD). We retrospectively reviewed patients who underwent ≥ 5-level fusion including the pelvis, for ASD with a ≥ 2-year follow-up. Using the Scoliosis Research Society-Schwab classification system, patients were classified into 3 groups according to the severity of the preoperative sagittal imbalance: mild, moderate, and severe. Postoperative clinical and radiographic results were compared among the 3 groups. A total of 259 patients were finally included. There were 42, 62, and 155 patients in the mild, moderate, and severe groups, respectively. The perioperative surgical burden was greatest in the severe group. Postoperatively, this group also showed the largest pelvic incidence minus lumbar lordosis mismatch, suggesting a tendency towards undercorrection. No statistically significant differences were observed in proximal junctional kyphosis, proximal junctional failure, or rod fractures among the groups. Visual analogue scale for back pain and Scoliosis Research Society-22 scores were similar across groups. However, severe group's last follow-up Oswestry Disability Index (ODI) scores significantly lower than those of the severe group. Patients with severe sagittal imbalance were treated with more invasive surgical methods along with increased the perioperative surgical burden. All patients exhibited significant radiological and clinical improvements after surgery. However, regarding ODI, the severe group demonstrated slightly worse clinical outcomes than the other groups, probably due to relatively higher proportion of undercorrection. Therefore, more rigorous correction is necessary to achieve optimal sagittal alignment specifically in patients with severe baseline sagittal imbalance.

Evaluation of Soft Tissue Changes Following Orthognathic Surgery Using Virtual Surgical Planning Software.

Orthognathic surgery brings about a harmonious relationship between jaws, resulting in improved facial aesthetics. It is key to analyze if satisfactory results can be attained by using virtual surgical planning for orthognathic procedures so as to recommend it for routine clinical practice. The aims of this study were to evaluate the various soft tissue changes that take place following orthognathic surgery using three-dimensional (3D) imaging and virtual surgical planning software and quantify the accuracy of virtual surgical planning software on patients undergoing orthognathic surgery. This is an observational prospective study with a sample size of 12. In this prospective study, 12 patients undergoing orthognathic surgery were included following the inclusion and exclusion criteria. A usual pre-surgical work-up was done and a 3D replica of the facial skeleton was formulated using the software with the DICOM data acquired from the patient i.e., CT and scans of patient's dentition. Virtual surgical planning was done and splints were manufactured according to the desired newly achieved position. Patients were operated following the virtual surgical plan guided by the computer-aided design and computer-aided manufacturing (CAD-CAM) splints. Post-operative evaluation was done. As the study is more of a descriptive study to obtain detailed knowledge of a new procedure, only one group is being studied and hence there is no statistical testing included in this study. The mean discrepancy noticed after superimposition of soft tissue points was 0.92 with a standard deviation of 0.3. 3D CT virtual surgical planning is a reliable tool to achieve predictable and reliable post-operative results in orthognathic surgical cases.

Therapeutic Options in Hydatid Hepatic Cyst Surgery: A Retrospective Analysis of Three Surgical Approaches.

Hydatid disease is endemic in certain geographical areas where animal breeding is common, frequently challenging the medical services in these regions. Hydatid cysts most often affect the liver, with damage to other organs accounting for around one-third of the total cases. The alternative to interventional or pharmacological approaches is surgical treatment, available in variants such as laparoscopy, laparoscopy with special instruments for hydatid disease, or open surgery. This article aims to analyze the outcomes of these three types of surgical approaches, considering preoperative indications, operative techniques and efficiency, and immediate and long-term postoperative results. A total of 149 patients from two different surgical units were analyzed over a period of seven years. It was observed that males were more affected by this pathology (53.02%), with the majority of patients coming from rural areas (62.42%). The distribution by surgical procedure type showed that 50.34% were operated on using open surgery, 33.56% by means of a laparoscopic approach with the usual instruments, and 16.11% by means of a laparoscopic approach with special instruments. The laparoscopic procedure with special instruments presented a lower rate of conversion to open surgery compared to the usual laparoscopic approach (p = 0.014). The analysis of the average operative duration revealed statistically significant differences between the three types of surgical techniques (p < 0.05), noting that interventions with specialized instruments had the shortest duration, while open surgery had the longest operative time (72.5 ± 27.23 min vs. 154 ± 52.04 min). In terms of intraoperative complications, they were documented in 8.34% of cases for the group operated on with special instruments, in 12.24% of cases for the standard laparoscopy group, and in 16% of cases for the open surgery group. Maximal cystectomy was the preferred method for resolving these cysts using minimally invasive surgery (p < 0.001), while Lagrot pericystectomy was preferred in the open approach (p < 0.001). The most frequent postoperative complication was biliary fistula (24.16%), encountered in varying percentages across each technique but without significant statistical difference (p > 0.05). Open surgery was associated with a longer length of hospitalization compared to minimally invasive procedures (p < 0.05), a higher number of late postoperative complications (p = 0.002), and a significantly higher number of recurrences (p < 0.001) compared to the other two techniques. The present study highlights the effectiveness of minimally invasive surgery for hydatid cysts as a safe alternative with fewer complications and superior results compared to open surgery. Additionally, it provides a comparative analysis of these surgical approaches (special instruments, standard laparoscopy, and open surgery) to hydatid disease for the first time. Under the circumstances where pharmacological treatment is recommended as a supportive measure before and after procedures, and using medication alone as the primary treatment option shows only modest efficacy, there is a necessity to consider invasive treatment methods. Percutaneous procedures represent the least invasive form of treatment, yielding results comparable to surgery in terms of efficacy. However, their effectiveness is influenced by factors such as the cyst's stage of development, its location, and the challenges in achieving complete intra-procedural isolation. Laparoscopy, particularly when using specialized instruments tailored to the tactical and technical demands of managing hydatid disease, serves to address the limitations of percutaneous methods. Open surgery's role is increasingly restricted, primarily serving as a fallback option in laparoscopic procedures or in cases complicated by hydatid disease. In conclusion, despite the rising popularity of percutaneous methods, surgery remains a viable therapeutic option for treating hydatid disease. Minimally invasive surgical interventions are increasingly versatile and yield comparable outcomes, further solidifying the role of surgery in its management.

Long-term outcomes of the BalMedic bovine pericardial bioprosthetic valve in female patients ≤50 years: a multicenter retrospective study.

A bioprosthetic valve is recommended for women of childbearing age who require cardiac valve replacement in order to minimize the risk of blood clot formation. However, it should be noted that compared to mechanical valves, bioprosthetic valves have a shorter lifespan and a higher likelihood of requiring reoperation during follow-up. To assess the long-term postoperative results, including the incidence of structural valve deterioration (SVD) and other clinical outcomes, in female patients aged 50 years and younger who underwent BalMedic bovine pericardial bioprosthetic valve replacement, a multicenter retrospective study was implemented in China. Between 2004 and 2015, a cohort of 86 female patients across three medical centers underwent the implantation of 97 bioprosthetic valves. The primary outcome measure was overall survival (OS), while the secondary outcome measures were preliminary evidence of reoperation, SVD incidence, and bioprosthetic valve-related complications. In this cohort study, 21 patients (24.4%, 21/86) died, while 37 patients (43.0%, 37/86) underwent a second valve replacement. The OS rates at 5 and 10 years were 97.56% and 71.93%, respectively. Additionally, the reoperation-free rates at 5 and 10 years were 92.83% and 80.68%, respectively. Similarly, the rates of freedom from SVD at 5 and 10 years were 95.65% and 51.82%, respectively, and the average duration of bioprosthetic valve replacement in our study was 9.34±3.31 years. Despite the recruitment of younger female patients of child-bearing age in our cohort, the OS, reoperation-free survival, and SVD-free rates of the BalMedic bovine pericardial bioprosthetic valve were not inferior to those of the other age groups in the study or those reported in the literature.
